Dear maintainer:

During a rebuild of all packages in unstable, this package failed to build.

Below you will find the last part of the build log (probably the most
relevant part, but not necessarily). If required, the full build log
is available here:

https://people.debian.org/~sanvila/build-logs/202603/

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you cannot reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:liquidsoap, so that this is still
visible in the BTS web page for this package.

Thanks.

There might be two issues here:

1. libffmpeg-ocaml apparantly has stricter FFmpeg dependencies than the
shlibs-generated ones due to depending on additional ABI details (why?).

2. liquidsoap does not have a dependency on libffmpeg-ocaml-<ABI>.

There is an upstream release that fixes the actual build failure that I
have staged in git. However, I'm still unsure why dh-ocaml isn't picking
up the ffmpeg dependency and adding it in as I would expect. All my
investigation seems to point to ffmpeg support being included in the
build, and so the dev dependency is correctly found by dune's build
process. It then doesn't seem to make it into dh_ocaml's output variables.

If anyone has any insight into why dh_ocaml isn't doing what I expect,
that would be most appreciated.

I suspect libffmpeg-ocaml is (statically) linked into the liquidsoap
executable, and not referenced by the libraries installed by the
liquidsoap binary package.

By the way, the <ABI> in libffmpeg-ocaml-<ABI> is automatically computed
by dh_ocaml *over the OCaml interface only*. If libffmpeg-ocaml depends
on additional ABI details of ffmpeg, then probably something special has
to be done, and it depends on what these "details" are.


Cheers,

Yes, that appears to be what is happening - ffmpeg forms part of the
liquidsoap core that produces /usr/bin/liquidsoap and not any additional
ocaml libraries. Is there a way to get dune to link to the shared
library instead of statically linking to ocaml-ffmpeg?

supported only for plugins (à la dlopen) and an executable that wants to
use shared libraries has to be explicitly designed to do so.

But there is another problem to be solved first: one has be sure that
the ABI in libffmpeg-ocaml-<ABI> encompasses the "ABI details" of ffmpeg
it depends on.
